I was trying to update my dx58so motherboard bios version 4598 to version 5599. The bios update finished after 2 minutes using the .exe update, but right after the update i got a black screen. After waiting 10 minutes with the black screen and nothing happining i shut down the pc.
Now my pc are stuck in the "intel screen" showing the number 5A (see picture) and evrey time that i press a keyboard key i got one beep sound.
So, what went wrong and what i have to do? Please help me
